Application Scenarios & Design Considerations

16-bit Proprietary Microcontroller

Alternative Part Number

  • MB90F387SPMC --: Same Fujitsu 16-bit F2MC-16LX family MCU with comparable flash and peripherals; widely available and pin/function compatible for many MB90F462A designs.
  • MB90349CASPFV --: F2MC-16LX series MCU with similar core, flash size and peripheral set; a practical drop-in candidate when the exact MB90F462A is unavailable.
  • MB90F543GSPMC --: Another F2MC-16LX family device with comparable flash and I/O resources; usable as a functional substitute after pinout and peripheral verification.
  • MB90F462APMC --: Same MB90F462A core in the PMC package variant, pin-compatible with the original and widely available as a drop-in replacement.
  • MB90F462APFV --: Same MB90F462A family in the PFV (QFP) package, offering identical functionality with a different package option for layout flexibility.
